The aim of this project is to develop a comprehensive approach, to produce large wind turbine blades fully recyclable and sustainable. To tackle the waste issue of wind turbine blades and reduce the CO2 emissions, the WiseWind project aims to provide the material basis for a new type of wind turbine blades, fully recyclable, which will be easily separated into high performance glass fibres and polymer resin. To identify a promising recyclable resin and introduce it in the manufacturing of large wind turbine blades, a number of innovations are required. To assist and optimize the production and recycling of wind turbine blades using the new resin, the WiseWind project will develop a computational model and digital twin of the wind turbine blade composites from cradle to grave. This model will support the adjustment of curing profiles limiting residual stresses and ensuring the best fatigue properties for the blades. The model will also provide processing conditions for the recycling processes considering several techniques. To validate the sustainability of the new resin, environmental impacts will be characterized, a cost analysis will be performed and additional social parameters will be quantified. With the existing recycling technologies, current blades mostly end in landfill. The project will help reducing the 325 ktons of blade waste predicted in 2050 in Europe [1]. The WiseWind project will also contribute to reduce CO2 emissions originating from wind turbine blades.

Soybean imported from countries with little environmental regulation is currently the main protein source in pig feeds and should be replaced by local protein sources. In this project, a feed supplement, DP5, will be developed for the Danish and international market using a technique where amino acids (AA) are chemically bound to sugars to reduce absorption rate and improve utilization compared to synthetic free AA. The feed supplement is developed to complement the AA profile of local protein ingredients to fulfill the animals AA requirements. This will allow a reduction in the total use of dietary protein in the pig production and increase the use of local feed ingredients as alternatives to soybean meal. A 20% reduction in N excresion, 20% less water use and 63% less C-footprint is predicted along with a value for the pig producer of approx. 23 DKK/pig though mainly improved feed efficiency. A version of this new feed supplement is developed in work package one (WP1). The preliminary version of this product will be investigated to evaluate the physiological aspects and the quantitative impact on growth, nutrient utilization and gas emissions from the pigs in an experimental setting (WP2). Hereafter, the product will be refined based on the results of WP2 and the impact of using this refined feed supplement is then assessed under commercial conditions (WP3). The above-mentioned activities (WP) will be coordinated in close collaboration between the WP leaders (WP4).
